Answer:

Step-by-step explanation:

Well you can get rid of c and d since 9^2 = 81. so 74 is less than 81 so it's definitely less than 9. Now, we know it's between 8 and 9. try multiplying 8.5 x 8.5 = 72.25. So our ranges are

A) 64 - 72.25

B) 72.25 - 81.

74 falls between 72.25 - 81. So it'll be B

Answer:

X= -9

Y=7

Z=119

X=-70

Y=0.8

z=4.667

Step-by-step explanation:

X=-18-6= -24/3= -9

Y=24+11/5= 35/5= 7

Z=10+7=17*7=119

X=-2-5=-7*10=-70

Y=19-7=12/15=0.8

Z=-2+4=2*7=14/3=4.667

Select all of the statements that are true for the given parabola.

svet-max [94.6K]

Answer:

A and B

Step-by-step explanation:

The minimum occurs at the turning point ( vertex )

The coordinates of the vertex are (1, - 2 ) → A

The x- intercepts are the points where the graph crosses the x- axis

This occurs at (3, 0 ) and (- 1, 0 ) → B

The axis of symmetry is a vertical line passing through the vertex

Equation of axis of symmetry is x = 1 , not y = - 2

(1, - 2 ) is a minimum not a maximum , see above

Is it a, b , c , or d?

The line has a positive slope. Let's look at all the slopes:

1) -3

2) -3

3) 3

4)3

Which ones are positive? That's right, 3 and 4. We don't know which equation would be the equation of the line. That's where the other information comes in.

The line intersects the y-axis at at a point that has a negative y-coordinate. Lets write the last two equations in slope-intercept form.

1) y = -3/2x - 5/2

2) y = -3/2x + 5/2

We have to graph both of the lines now. The graphs are at the very bottom. Take a look at them. In the first one, the y-intercept is a negative and in the second one, the y-intercept is positive.

The third one AKA 3x + 2y = -5 is the equation of the line. I hope this helps! Let me know if I got it wrong or if you need any more help.
